What are the official collapse theories? Can they account for the total collapses and for specific features documented by physical evidence? How scientific were the investigations that produced these theories?

Presenter is: Jim Hoffman, M.F.A., Former research scientist, published in Science and Macromolecules for research in polymer physics, and Communications of the ACM for visualization software, and creator of 9-11 Research, the highest-ranking website challenging the core tenets of the official story of 9/11.
